The reflectivity of the textured surface is still as high as 30%, which does not meet the production requirements of industrial solar cells. The surface reflectivity of the silicon wafer is required to be below 25
So that the velvet surface reflectivity is still 30% high, does not meet the industrial preparation of solar cells production requirements, the need for silicon surface reflectivity of less than 25.
The results show that the reflectivity of the velvet surface is still as high as 30%, which does not meet the production requirements of industrial solar cells, and the surface reflectivity of silicon wafers is less than 25
